ZIP_SOURCE_ZIP(3)	 BSD Library Functions Manual	     ZIP_SOURCE_ZIP(3)

NAME
     zip_source_zip -- create data source from zip file

LIBRARY
     libzip (-lzip)

SYNOPSIS
     #include <zip.h>

     zip_source_t *
     zip_source_zip(zip_t *archive, zip_t *srcarchive, zip_uint64_t srcidx,
	 zip_flags_t flags, zip_uint64_t start,	zip_int64_t len);

DESCRIPTION
     The function zip_source_zip() creates a zip source	from a file in a zip
     archive.  The srcarchive argument is the (open) zip archive containing
     the source	zip file at index srcidx.  len bytes from offset start will be
     used in the zip_source.  If len is	0 or -1, the rest of the file, start-
     ing from start, is	used.  If start	is zero	and len	is -1, the whole file
     will be copied without decompressing it.

     Supported flags are:

     ZIP_FL_UNCHANGED	    Try	to get the original data without any changes
			    that may have been made to srcarchive after	open-
			    ing	it.

     ZIP_FL_RECOMPRESS	    When adding	the data from srcarchive, re-compress
			    it using the current settings instead of copying
			    the	compressed data.

RETURN VALUES
     Upon successful completion, the created source is returned.  Otherwise,
     NULL is returned and the error code in archive is set to indicate the er-
     ror.

ERRORS
     zip_source_zip() fails if:

     [ZIP_ER_CHANGED]	Unchanged data was requested, but it is	not available.

     [ZIP_ER_INVAL]	srcarchive, srcidx, start, or len are invalid.

     [ZIP_ER_MEMORY]	Required memory	could not be allocated.
     Additionally, it can return all error codes from zip_stat_index() and
     zip_fopen_index().
